Just reflash the rom you are on. You don't need adb.
I don't think I can do that, because I don't have any zips. I have a factory zip on my PC, and I simply need to get it on the phone. I can't find a image of CWM or TWRP for my Asus ZenPad S 8.0, but I found a script that temporarily flashes some version of CWM recovery to my phone. I have a custom recovery available for use, but now need some way to get my zip to my tablet so I can extract it. That's where I'm stuck. If ADB was authorized, I would just push the file and install it. Here's the options as I see them
1: Authorize RSA via CWM Recovery (Which is why I'm here..)
2: Find a version of CWM or TWRP or some other recovery compatible with my tablet, and try again. Hope it's more updated, and cross my fingers.
3: Use an external microSD card to move the zips. (Doesn't work. E:Can't mount /external_sd/. I tried FAT32 and tried formatting with a different android device which used exFAT. No luck)
4: Somehow fix operating system to approve RSA. (Safe mode failed)
I hate to say it, but I think the tablet may have won this war unless I'm missing something. Thanks for your help though! And Merry Christmas! I'll be over at XDA Assist...
